Computer Science Consultant
Jeff Klingner is a computer scientist and consultant
for HRDAG. He earned a Ph.D. in Computer Science at Stanford University,
where he received a National Science Foundation graduate research
fellowship.
Dr. Klingner has collaborated with HRDAG since 2005. He performed data analysis and created visualizations of document flow within the Chadian government in the 1980s, establishing that the president of Chad was in control of the country's secret police and was well-informed of hundreds of deaths that occurred in police prisons.
He implemented data-cleaning and conducted analysis of several sources of data collected by Ensaaf in Punjab, India, establishing verifiable quantitative findings on mass disappearances and extrajudicial executions during the Sikh uprising and resultant police and army crackdown of 1984-1995.
Dr. Klingner designed and wrote a machine-learning
software package for de-duplicating and merging lists of violent
deaths and other human rights violations. HRDAG has applied this
technology to many analyses, including its work in Colombia,
El
Salvador, Liberia
and Sierra
Leone.
Dr. Klingner's contributions to HRDAG also include
data mining, visualization, survey estimation, inter-rater reliability
analysis and a multiple systems estimation simulation package.
